Aspnetcore: [Blazor 0.9.0] How to switch between ASP.NET Core Razor Components and client-side Blazor on 0.9.0?

[ctrl-alt-d]

I have found instructions to switch between ASP.NET Core Razor Components and client-side Blazor for 0.8.0 at Server-side Blazor is now ASP.NET Core Razor Components in .NET Core 3.0

I miss this information on "Upgrade to Blazor 0.9.0" blog post.

I tried 0.8.0 instructions, unsuccessfully, on 0.9.0: https://github.com/aspnet/AspNetCore/issues/8440

Question is: How to switch between ASP.NET Core Razor Components and client-side Blazor on 0.9.0?

Thanks for contacting us, @ctrl-alt-d.
@danroth27 did the way to change between Blazor and Razor Components change?

Unfortunately it looks like there isn't really a good way to do this with Blazor 0.9.0 and Razor Components in .NET Core 3.0 Preview 3 :-(. We need to get this fixed for Preview 4. I believe https://github.com/aspnet/AspNetCore/issues/8852 should make this scenario reasonable again. @stevesandersonms Can you confirm?

As long as you're not doing prerendering, I don't think there's anything stopping you from switching like that. Our E2E tests already do switch between server and client execution: https://github.com/aspnet/AspNetCore/blob/master/src/Components/test/testassets/TestServer/Startup.cs.

I recognize that people still want a simpler sample of how to do this, so I'll leave the issue open until we have one.

Since the original question is about Blazor 0.9 we've closed this, as we have some other issues to track improving this experience for the upcoming releases.

didn't have any info about this issue, maybe we should add example of switch cliend-side \ server-side.
